There is a pill at the pharmacy called "Chaser" it is pretty dang good. Raw clams is another sure fire way to clear up your tummy, the clams absorb all the bad stuff still in the gut. A straight shot of oxygen helps clear the head. And one Bloody Mary will do wonders.
Abstain from alcohol! But, I use to use homemade lemon juice, with sugar, and fresh lemon with every glass. Eat the lemon, but not the rind. Also, food is great for absorption of the alcohol. Tylenol in the morning, small amounts of crackers, or sandwich, potatoes, but not deep fried, worst thing for you that way. Pasta is good for some people, just basically whatever you can get to sit on your stomach, but if you are getting sick, stick with small amounts of food. Hope this helps.
